Homology to Nominate a Clinical Development Candidate for MLD This Quarter and to Begin IND-Enabling Studies in 2019

BEDFORD, Mass., Nov. 07, 2018 (GLOBE NEWSWIRE) -- Homology Medicines, Inc. (Nasdaq: FIXX), a genetic medicines company, announced today data demonstrating that Homology’s proprietary vectors are able to cross the blood-brain-barrier and have a positive impact on the rare neurological disorder metachromatic leukodystrophy (MLD). The presentation at the Society for Neuroscience (SfN) 2018 Annual Meeting reported biodistribution data on three of Homology’s 15 human-derived adeno-associated virus vectors (AAVHSCs). Following a single intravenous (IV) injection in a large species, the AAVHSCs demonstrated transduction of a variety of peripheral and central nervous system tissues and cell types. Additionally, in the preclinical MLD model, a single IV injection of a Homology vector led to 30-115% of normal human ARSA enzyme activity levels, exceeding the established therapeutic target of 10-15%. Homology plans to nominate an MLD development candidate this quarter and to begin IND-enabling studies in 2019.

“The key requirement for developing single IV gene therapies for neurological disorders is the ability for the therapeutic to cross the blood-brain-barrier, and we are pleased to report that our vectors effectively reach the central and peripheral nervous system following systemic administration,” said Albert Seymour, Ph.D., Chief Scientific Officer of Homology Medicines. “We are striving to provide a one-time treatment option that may lead to a cure for patients, and these preclinical data are informing our plans to nominate a development candidate by the end of the year.”

About Metachromatic Leukodystrophy (MLD)
MLD is a rare lysosomal storage disorder caused by a mutation in the ASA gene. ASA is responsible for the creation of the arylsulfatase A (ARSA) protein, which is required for the breakdown of cellular components. In MLD, these cellular components accumulate and destroy myelin-producing cells in the peripheral and central nervous system leading to progressive and serious neurological deterioration. The late infantile form of the disorder is estimated to affect 1 in 40,000 people, and it is fatal within 5-10 years after onset.
